ROLLING SPECIFICATION forming part ofIetters Patent No. 255,081, datedMarch 14, 1882 'COLTER.

Application filed December 9, 1881. (No model.)

To all whom it may concern Be it known that I, FRANKLIN B. HUNT, of

Richmond,in the county of Wayne and State of Indiana, have inventedcertain Improvements in Rolling Oolters, of which the following is aspecification.

My invention relates to improvements in journalin g circular colters tothe yokes by which they are secured to plows to adapt them to withstandthe increased strains to which they are subjected by use uponwheel'plows, and also to provide ajourna-l and bearings which willoperate without the use of oil, allas hereinafter fully described andset forth in the specification and claims.

Figure 1 is a longitudinal vertical section through the axis of thecolter and adjacent mechanism. Fig. 2 is a perspective of thecolter-shank and a portion of the upper end of the yoke by which thecolter is suspended. Fig. 3 is a perspective of the colter-shank bywhich the col ter is suspended from the plowbeam. Fig. 4 is a planot'one-half of the colteryoke. Figs. 5 and 6 are longitudinal sectionsof modifications of the invention.

A is the rolling colter. B is the shank by which the colter is suspendedfrom the plowbeam by means of the arms 0, forming a colteryoke. Thesearms 0 are cast in pairs, one of which is seen at Fig. 4., and providedwith the hollow part P, which hollow parts P are provided with cups orrecesses H for the cushions I, as seen in Figs. 1, 5 and 6. The upperends of these arms 0 are provided with an elongated head, T, as seen inFigs. 2 and 4. These elongated ends are provided with holes F for thebolts G. The center of this head is provided with a half-circle hearingor recess, E, which, when the arms are put together and in place,forms'acircle and fits on the neck F ofthe shank B to form acolter-yoke. The neck F is pro, vided with an elongated head, D, whichrests between the arms 0, as seen at Fig 2, and, being slightly taperingtoward the ends, allows the arms 0, forming the colter-yoke and carryingthe colter, to vibrate sufficiently for the colter to adjust itself atall times to the line of draft, and also holds the yoke upon the neck Fof the shank B. The arms O are cast, preferably of steel,to stand greatstrain, and formed ready for use without fitting, and provided with theholes F F, recesses E for the neck F, and recesses H for the cushions I.Figs.5 and 6 are modifications of Fig. 1. In Fig. 1, J arcjournals withflanges to rest against the colter, and attached thereto in any suitablemanner. The bearings K K for the journals J are made of hard wood, andboiled in tallow and plumbago to form a bearing for the journals whichdoes not require oil, this being a great desideratum, as thecarelessness or neglect of operatives to properly oil the journals of arolling colter causes it to cutout rapidly, as it is continually exposedto dirt and grit from the soil. The cushions 1 rest against the flangesof thejournals J. The cups or recesses H extend over the cushions andembrace the edges of the flanges. The shoulders or hottoms M of the cupsH press against the outer portion of the cushions, and the woodenbearings K press against the inner portion of the cushions by means ofthe hollow screw-plugs L L pressing against thebearings. The bolt N hasits bearing in the hollow screw-plugs L L alone to prevent all contactor frictionwith the bearing J J and KK,'and it will be readily seen thatthe office of this bolt is to clamp the outer edge of the cushionsthrough the means of the screw-plugs L and bottom M of the cups orrecesses. The socketed parts P P, attached to the lower ends of thearms'O, are threaded at their outer ends. to receive the hollowscrew-plugs L L. The inner edges of the recesses H lap over the edges ofthe flanges of the bearing J, and keep out the greater portion of thedirt, and the cushions fitting snugly in their places, as plainly seenat Fig. 1, makea journal-bearing absolutely dust-proof.

The cushions I may be made of leather, rubber, or any suitable material.

The wooden bearings K may be replaced with metal bearingsfand oil used,if desired, as the journals arefree from dust; butI greatly prefer thewood, as it suffers no harm from neglect.

The inner surfaces of the'socketed parts P P for the bearings Kma y bemade square, octagonal, or any other desired shape.

Fig. 6 represents another construction of wooden bearings for thecolter-journal, with I00 cups or recesses, as above, attached to thearms O for the cushions I, and provided with wooden hearings K andscrew-plugs L.

Fig. 5 represents threaded metal bearings "R R, held in place, whenadjusted, by means of B, provided with the neck F, and elongated head D,and bolts G, substantially as set forth.

2. In combination with the journal of the rolling" colter A, the cups H,cushions I, bearings K. andscrew plugs L, substantially as set forth.

3. In combination with the rolling colter and the'socketcd part P, thecushions I, wooden bearings K, and screw-plugs L, substantially as setforth.

4. In combination with the rolling colter and socketed part I, thewooden bearings K K, hollow screw-plugs L L, and bolt N, substantiallyas shown and described.

5. In combination with the socketed part P and the bearings J of therolling colter, the wooken bearings K, cushions I, and screwplugs L,substantially as set forth.

6. The cups H, arranged to pass beyond the cushions I and embrace theflanges of the bearings J, in combination with said cushions, bearingsK, and screw-plugs L, substantially as shown and described.

7. The cups H, arranged to pass beyond the cushions I and embrace theflanges of the bearings J, in combination with said cushions, bearingsK, screw-plugs L, and bolt N, substantially as set forth.

8. In combination with the arms 0 O and socketed portionsIP, providedwith the screwplugs L L, the boltN, substantially as shown anddescribed.

9. In combination with the arms 0 O and socketed portions P P, providedwith thescrewplugs L L and cups or recesses H H, the bearings J K,cushions I I, and bolt N, substantially asset forth.

10. In combination with the socketed portions P I, provided with therecesses H and cushions I, the screw-plugs L L, and bolt N,substantially as shown and described.
